Abstract

L'invention concerne un système d'ombrage transparent motorisé pouvant déplacer un matériau d'ombrage transparent entre une position ouverte, une position fermée et une position de vision. Le système d'ombrage peut déplacer le matériau d'ombrage transparent de la position ouverte vers la position fermée à une première vitesse de rotation moyenne et de la position fermée à la position de vision à une seconde vitesse de rotation moyenne. Le système d'ombrage peut déterminer automatiquement une limite de commande qui correspond à la position fermée du matériau d'ombrage transparent une fois les limites de commande définies pour la position ouverte et la position de vision. Le système d'ombrage peut amener le matériau d'ombrage transparent à cesser de se déplacer une fois qu'il a atteint la position fermée si le bouton d'élévation d'une commande à distance est encore enfoncé et peut amener le matériau d'ombrage transparent à cesser de se déplacer une fois qu'il a atteint la position fermée si le bouton d'abaissement de la commande à distance est encore enfoncé.
